FIREPRO OF PARTITION FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 682,274, datedSeptember 10, 1901.

To all whom it may concern.-

Be it known that I, SAMUEL E. RABBITT, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Fireproof Partitions forBuildings; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to the construction of buildings, has especialreference to partitions, has for its object a fire, rat, germ, andvermin proof structure, presenting a solid composite partition of metaland plastic material, preferably cement, which shall be as thin aspracticable to secure strength and rigidity, and consists in certainimprovements in construction, which will be fully disclosed in thefollowing specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents an elevation of a partition embodying my invention,showing on part thereof the studding in position without the lathingapplied, a double partition or pocket for a sliding door, the lathing,and the plastic material applied to the studding on another partthereof; Fig. 2, a perspective, on an enlarged scale, showing the mannerof constructing a double partition and pocket for a sliding door; Fig.3, a vertical transverse section of the partition before the metalliclathing is applied, showing the lateral braces between the studs abovethe door-opening and the door suspended, as it appears after thepartition has been completed. Fig. 4 is a perspective, on an enlargedscale, showing part of one stud and a lateral brace secured thereto.Fig. 5 is a perspective showing a stud with several different clipsattached; Fig. 6, a transverse section, on a reduced scale, through thestud, the clamp, and the post on line 6 6, Fig. 5. Fig. 7 is aperspective of one of the clips for securing the door-frame to themetallic stud adjacent thereto; Fig. 8, a like view of a clip forsecuring a washboard-base strip to the studs; Fig. 9, a like view of aclip for securing wire lathing or expanded metal to the studs, and Fig.10 is a plan View of the blank from which the latter clip is made.

Reference being had to the drawings and the designating charactersthereon, 1 indicates metallic studs, preferably of the form shown,described, and claimed in my application for a patent filed April 20,1901, Serial No. 56,735; but any other approved form of stud may beused.

The studs are in two sections connected by a coupling 2 and are providedwith adjustable clips 3, which in this instance consist of a band 4:,having inwardly-bent flanges 5 to engage the side ribs 6 of the metallicstud, and one or more separate straps 7, which are inserted between theband 4. and the stud to engage the metallic lathing. The constructionand the application of this clip are clearly shown in Figs. 5 and 9 inenlarged views, and the general application of the clips to the studsand the lathing is shownin Fig. 1. The clips are loose on the studs, sothat they may be readily adjusted thereon to suit the interstices in thelathing, through which the straps 7 are inserted and bent back upon thelathing, as shown at the upper right-hand corner of Fig. 1 and at theleft end of the same figure, in which a partition at a right angle tothat shown in elevation is shown secured to the latter by the straps ofthe clips 3 engaging the metallic lathing 8.

To provide a base for the washboard 9,strips of wood 10 are securedbetween the studs 1 by clips 11, which are provided with flanges 12,bent to engage the sidefiribs tilof the studs, and with arms 13 toengage the ends of the strips 10, and are secured thereto by nails,

and thereby forms an effectual base embedded in the plastic material 14and to which the tion described effectually overcomes this difficultyand provides a practical way of securing the base so that it cannot bedisplaced or loosened. Another difficulty has been found in securing thepost of a door-frame to the stud adjacent thereto to prevent the framebecoming loose and the jar of the door breaking the plaster. To overcomethis, I provide clips 15, which are placed at suitable intervals on thestud to secure the post 16 rigidly thereto. This clip is provided withflanges 17 and 18, cut out of the body of the metal and bent to engagethe side ribs 6 of the stud, as shown in Figs. 6 and 7, and the ends ofthe clips engage and are secured to the post 16. The flanges 17 and 18secure the clip to the stud, so that the clip cannot move laterally, andthe clip secures the post to the stud by the ends of the clip embracingthe sides of the post. This clip is also used to secure a stud to abrick wall, as shown on the righthand side of Fig. 1.

To provide a smooth inner surface for each partition in the pocket inwhich a sliding door works, false doors or dummies 19 and 20 areemployed and are pushed into the pocket, separated, and held against theinner faces of the studs 1, as shown in Fig. 2, by strips or wedges 21,when the plastic material 14 is applied to the metallic lathing 8 anddriven through its interstices until it packs against the false doors,when it is allowed time to set, after which the false doors are removedand a smooth inner surface of the partition is provided.

To stiffen the double partitions beyond the door-pockets and above thedoor-opening 26, vertical and lateral metallic braces 27 are insertedzigzag or crossed alternately and secured to the studs 1 by clips 28,(also provided with straps 7,) which braces effectually resist lateralmovement of the partitions, and in the space 29 above the door thebraces extend to and are secured to the ceiling above at one end and tothe rail-support 30 at the opposite end, as shown in Fig. 3, whereby theweight of the door 31 is partly sustained by the braces 27. Therail-support is also secured to the studs 1 by clips 32 or in any othermanner. The rail 33 is secured to the rails'upport in the usual way,'andthe door is provided with rollers 34, which engage the rail.

In the rear of each door-pocket 25 transverse blocks 35 are insertedbetween opposite studs 1 to form a stop for the door and prevent itsbeing pushed in too far, as shown in Figs. 1 and 2, and in which, Fig.1, one of the doors 31 is shown in a pocket in the skeleton partition.

Having thus fullydescribed my invention, what I claim is- 1. A partitionconsisting of metallic studs extending from a floor to a ceilingprovided with base-boards between and secured to the the studs by clips,and metallic lathing secured to the studs; in combination with plasticmaterial embedding the studs and the lathin g.

2. A partition consisting of metallic studs, a door-frame having amember secured to a stud by clips engaging the stud and embracing thesides of said member, and metallic lathing secured to the studs; incombination with plastic material embedding the studs and the lathing.

3. A double partition consisting of metallic studs, vertical and lateralzigzag or crossed metallic braces between the studs of the twopartitions and secured thereto by clips, and

metallic lathing secured to the studs; in com-- bination with plasticmaterial embedding the studs and the lathing.

4. A double partition consisting of metallic studs, vertical and lateralmetallic braces between the studs of the two partitions and securedthereto, a track-rail support engaged by one end of said braces,metallic lathing secured to the studs, and plastic material embeddingthe studs and the lathing.

5. A double partition consisting of studs, a track-rail support betweenthe studs, braces securedat one end to the ceiling above and at theopposite end to said track-rail support and secured to the studsintermediate its ends, lathing secured to the studs, and plasticmaterial embedding the studs and the lathing.

6. A clip for securing metallic lathing, consisting of a body-piecehaving flanges to engage a metallic stud, and a separate strap engagingthe body.

'7. A clip for securing metallic lathing, consisting of a body-piecehaving flanges to engage a metallic stud, parts extending beyond thestud to engage another member of the partition, and a separate strapengaging the body for securing lathing to the stud.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL E. RABBITT.
